Bushings now come in NEW SIZES. On
most RKP (reverse kingpin) trucks like Bear, Caliber, Paris, Randal, Sabre,
etc. they recommend using a combination
of a 550 (Conical or Barrel) on the Top and
then 650
(Conical
or
Barrel) on the Bottom.

The 750's are
extra tall and are used on high-end trucks like Frye and Liquid. These tall
.750" bushings require longer kingpins and
allow for an incredible range of articulation.
